Infection
-
We compared standard antibiotic use with an antibiotic policy based on selective decontamination of the digestive tract (SDD) for cost and microbiology. ⋯ The overall cost per patient treated during an antibiotic policy including SDD was equal to a policy supporting standard antibiotic care. In addition, duration of ventilation decreased and a trend was shown towards a decreased Length of ICU and hospital stay. Less frequently, cultures from organ sites containing AGNB were found during SDD and the number of multi-resistant strains was significantly reduced at organ sites, in particular trachea and urine. Fewer patients were colonized with multi-resistant AGNB but these numbers did not reach statistical significance.
